Ukuguqula indlela yendabukoImodulator yeLiNbO3
Kutshanje, iqela lophando eTshayina lipapashe ipatent entsha yeteknoloji yokutshixa i-laser frequency kusetyenziswa i-LiNbO3 modulator. Eyona nto iphambili kule patent yinkqubo entsha yokutshixa i-laser frequency yePDH (Pound Driver Hall) eguqula iindlela zemveli.
1. Amanqaku entlungu yobuchwepheshe bendabuko:
Iinkqubo zesiqhelo zokutshixa iifrikhwensi zePDH zihlala zisebenzisa i-lithium niobate (LiNbO3)i-electro-optic modulatorukuvelisa iibhendi ezisecaleni ze-optical ezifunekayo. Le ndlela ineengxaki ezintathu eziphambili: iindleko eziphezulu kunye nesakhiwo esintsonkothileyo (esifuna iisekethe zomqhubi ze-RF ezintsonkothileyo), uvakalelo kwindalo esingqongileyo (utshintsho lobushushu kunye noxinzelelo lunokukhokelela ngokulula ekusebenzeni okungazinzanga), kunye neziphumo ze-residual amplitude modulation (RAM), ezinokubangela ukushukuma kwesignali yokutshixa kwaye zichaphazele kakhulu uzinzo lwexesha elide lwenkqubo.
2. Izisombululo ezintsha:
Amaqela ophando aseTshayina ayishiyile ngokupheleleyo i-electro-optic modulator yendabuko. Uyilo oluphambili lusekwe kuyilo oludibeneyo lwe-"semiconductor optical amplifier (SOA amplifier) edityaniswe ne-dual channel acousto-optic frequency shifter (AOM modulator)". Umgaqo othile ngulo: emva kokwahlulahlula i-seed laser beam, ezimbiniImodyuli ye-AOMZisetyenziselwa ukutshintsha ngokuchanekileyo i-frequency, kwaye ezi beams zimbini zokukhanya zifakwa kwi-SOA amplifier kwimeko ye-gain saturation. Zenza ngokufanelekileyo isignali ye-multi sideband efunekayo kwi-PDH frequency locking ngokusebenzisa iziphumo ezingezizo ezi-linear ezifana ne-four wave mixing (FWM) ngaphakathiIsikhulisi se-SOA.
3. Iingenelo zokusebenza ezibangelwa:
Uzinzo olupheleleyo: Izixhobo ze-SOA (ezifana nokupakishwa kwebhabhathane) zidibene nolawulo lobushushu kwaye azinangxaki nokuphazamiseka kwendalo, zisusa ngempumelelo iziphumo ze-RAM kwindlela ebonakalayo kwaye zifezekisa ukutshixa okuchanekileyo kakhulu kwexesha elide (kungcono kune-5 × 10 ⁻¹¹/ngosuku).
Umlinganiselo ophezulu wesignali-kwingxolo: Ngokulawula ngokuzimeleyo ukutshintsha kwamaza e-modulator ye-AOM ezimbini, kunokwenzeka ukufezekisa ukufana okuchanekileyo phakathi kwamaza asecaleni kunye nobubanzi be-spectral ekhululekileyo (FSR) ye-reference cavity, ngaloo ndlela kuphucula kakhulu umlinganiselo wesignali-kwingxolo wesignali yempazamo.
Ukunciphisa iindleko kunye nokunciphisa i-aturization: I-amplifier ye-SOA isusa ii-electro-optic modulators ezibizayo kunye neesekethe ezintsonkothileyo, ifuna kuphela ukuqhuba okulula kwangoku. Oku kwenza inkqubo ibe ncinci kwaye ingabizi kakhulu, nto leyo enceda ekufezekiseni ukuncipha kunye nokusebenza kwezixhobo.
4. Amathuba okusetyenziswa kunye nemfuno yemarike:
Le teknoloji ihlangabezana ngokuchanekileyo nemfuno enkulu yemithombo yelaser eqinileyo kakhulu kuphuhliso lwetekhnoloji ye-quantum, kwaye inamathuba amaninzi okusetyenziswa, kuquka:
Iwashi ekhanyayo efakwe kwindawo nakwisithuthi (kufuneka imelane nokungcangcazela okukhulu).
I-quantum gravimeter kunye ne-cold atom interferometer (esetyenziselwa ukuhlola i-geological kunye nokuhamba ngaphantsi kwamanzi).
Ukuqonda okuphambili kwe-fiber optic kunye ne-LiDAR.
Kwimarike yangoku, ingakumbi kwicandelo lophando lwezenzululwazi, ishishini lezomkhosi, kunye neenqwelo-moya zorhwebo, kukho ukwanda okukhulu kwemfuno yeemodyuli ze-laser ezizinzileyo nezilawulwayo ngokwazo, ezingabizi kakhulu, nezizinzileyo kakhulu ezivela kumashishini. Le teknoloji enelungelo lobunikazi iyibamba ngokuchanekileyo le ndlela yemarike.
